I have found recommended products are often no longer manufactured, and the latest products are seldom reviewed rapidly enough. And as a particular example, Consumers Reports discusses the advantages of "mild hybrid" cars (cars like Audis, BMWs, Mercedes with both 12V and 48V batteries, but not full hybrids that can electrically drive the wheels). But Consumer Reports fails to point out the significant cost of replacing these two batteries (even the 12V battery). Warranty coverage of the 48V battery is 3-4 years and replacement runs $3K-$4K. A significant cost of ownership.
